Page 16: Overall Operation
Introduction 1.1 Overall Operation Overall Operation The digital differential protection devices SIPROTEC 4 7UT6x are equipped with a powerful microprocessor system. This provides fully numerical processing of all functions in the device, from the acquisition of the measured values up to the output of commands to the circuit breakers [hardwarestruktur-270203-st, 1, en_GB] Figure 1-1 Hardware structure of the digital differential current protection relay 7UT6x —...
Page 17 Introduction 1.1 Overall Operation currents. One or two additional inputs can be designed for highly sensitive current detection. thus allowing, for example, the detection of small tank leakage currents of power transformers or reactors, or — with an external series resistor — processing of a voltage (e.g. for high-impedance unit protection). The versions 7UT613 and 7UT633 are available with 4 voltage inputs.
Page 18 Introduction 1.1 Overall Operation Front Elements Devices with operator panel have light emitting diodes (LEDs) and a display screen (LCD) on the front panel to provide information such as measured values, messages related to events or faults, status, and functional status.
Page 19: Application Scope
Introduction 1.2 Application Scope Application Scope The numerical differential protection SIPROTEC 4 7UT6x is a selective short-circuit protection for transformers of all voltage levels, for rotating machines, for series and shunt reactors, or for short lines and mini-busbars with 2 to 5 feeders (depending on the version). Being a single-phase device, it can also be used for small busbars with up to 7, 9 or 12 feeders (depending on the version).
Page 20 Introduction 1.2 Application Scope can occur especially in power stations following (full) load shutdown and/or frequency reduction, is thus detected. An undervoltage and overvoltage protection is to be integrated into devices with voltage measuring inputs. A 4-stage frequency protection monitors the frequency from the measured voltages. A version for two-phase application is available for traction supply (transformers or generators) which provides all functions suited for this application (differential protection, restricted earth fault protection, overcurrent protection, overload protection).

Page 43 Functions 2.1 General from various measuring locations (this is the case for the high-voltage side S1 of the transformer, which is fed by M1 and M2), no sides are defined for the additional protected object. Nevertheless, other protection func- tions (not the differential protection) can act on it, such as the overcurrent protection (3-phase on M5), the earth overcurrent protection (1-phase on X4), or the restricted earth fault protection, which compares the triple zero sequence current from M5 with the earth fault current of X4.
Page 44 Functions 2.1 General NOTE When configuring the topology proceed exactly in the order given below. Some of the following settings and setting possibilities depend on settings performed before. In DIGSI the tabs (setting sheets) under Power System Data 1 should be edited from the left tab to the right. First of all, number the sides of the main protected object consecutively, next number the measuring loca- tions, beginning with those for the main object, then for the remaining.

Page 48 Functions 2.1 General stabilising winding should be protected separately (e.g. with time overcurrent protection). During setting of address 105 PROT. OBJECT = Autotransf., a stabilising winding can be included. The current transformer X1 in Figure 2-7 is not required. In order to realise an earth overcurrent protection or a restricted earth fault protection in this arrangement, you can feed the sum of the three currents measured at M3 to an auxiliary 1-phase current input of the device.
Page 49 Functions 2.1 General Assignment of 3-phase Measuring Locations After determination of the global data, the 3-phase measuring locations must be assigned to the sides of the main protected object.

The earth winding is included as a side due to the parameterisation. Table 2-2 Configuration Versions in an Autotransf.
Page 52 Functions 2.1 General The auxiliary inputs can be assigned to a side or a measuring location, or they can remain non-assigned.

Page 54 Functions 2.1 General In practice, the voltage assignment depends therefore on the voltages which the device is expected to receive and process. Of course, voltage transformers must be installed at the appropriate locations and connected to the device.

Functions 2.1 General [leistungsmessung-am-generator-en, 1, --_--] Figure 2-9 Power measurement at generator If you have the choice to assign a side or a measuring location to the main protected object as shown in Figure 2-9 (S1 is identical to M1), such assignment of the side is preferable, because the power can be set later directly in the (mostly known) reference values.
Page 56 Functions 2.1 General [phasenfolge-020904-rei, 1, en_GB] Figure 2-10 Phase rotation Temperature Unit The temperature of the hot-spot temperature calculation can be displayed in Celsius or Fahrenheit. This applies in particular for the output of the hot-spot temperature if you are using the overload protection with hot-spot calculation.

Page 58 Functions 2.1 General autotransformer bank as a separate side in order to establish a current comparison protection for each of the windings (refer also to Figure 2-7 and the respective notes under “Auto-Transformer Banks”), no settings will be presented for this side as they would have no meaning for this application. If in an auto-transformer side S3 or S4 is a compensation winding, the mode of connection is always assumed to be “D”, and only odd- numbered vector groups can be selected for these sides.
Page 59 Functions 2.1 General The primary rated voltage (phase-to-phase) 370 UN BUSBAR is important for voltage-dependent protection functions (such as overexcitation protection, voltage protection, frequency protection, power protection func- tions). It also influences the calculation of the operational measured values. The feeders of a busbar may be rated for different currents. For instance, an overhead line may be able to carry higher load than a cable feeder or a transformer feeder.
Page 60 Functions 2.1 General differ from the rated currents of the associated current transformers which latter will be entered at a later stage (current transformer data). Figure 2-12 shows the example of a busbar with 3 feeders. Additionally, a rated current for the entire busbar as the main protected object can be determined. The currents of all measuring locations assigned to the main object are converted such that the values of the differential protection are referred to this rated current of the main protected object, here the busbar.
Page 61 Functions 2.1 General correct display and transmission of measured values (voltages, powers). Similar considerations apply to address 409 UN-PRI U4. Current Transformer Data for 3-phase Measuring Locations The rated primary operational currents for the protected object and its sides derive from the object data. The data of the current transformer sets at the sides of the protected object generally differ slightly from the object data before-described.

Page 64 Functions 2.1 General For rated secondary currents please make sure that rated secondary transformer currents match with the rated current of the corresponding current input of the device. Rated secondary currents of a device can be matched. If summation transformers are used, the rated current at the outgoing side is usually 100 mA. For rated secondary currents a value of 0.1 A is therefore set for all feeders.

The 3- phase measuring location M3 is irrelevant for the restricted earth fault protection. Since the assignment of the 3-phase measuring loca- tions and of the auxiliary measuring location is also defined by the topology, you only need to set auto- connected for the restricted earth fault protection REF PROT.

Functions 2.1 General Further 1-phase Protection Functions The 1-phase protection functions evaluate the 1-phase measuring current of 1-phase additional measuring input. It is irrelevant in this context whether the connect current belongs to the main protected object or not. Only the current connected to the additional measuring input is decisive. The device must now be informed which current is to be evaluated by the 1-phase protection functions.

Functions 2.2 Differential Protection Differential Protection The differential protection represents the main protection feature of the device. It is based on current compar- ison under consideration of the transformation ratio of the transformer. 7UT6x is suitable for unit protection of transformers, generators, motors, reactors, short lines, also with feeders, and (under observance of the available number of current inputs) for busbar arrangements.

Page 96 Functions 2.2 Differential Protection nents are transformed into unequal secondary DC components due to different time constants of the secon- dary circuits. This produces a DC component in the differential current which increases the pickup values of the differential stage for a short period. Identification of DC Components A further restraint comes into effect when differential secondary currents are simulated by different transient behaviour of the current transformer sets.
Page 97 Functions 2.2 Differential Protection The differential protection of the 7UT6x provides such an unstabilised high-current trip stage. This stage can operate even when, for example, a considerable second harmonic is present in the differential current caused by current transformer saturation by a DC component in the fault current, which could be interpreted by the inrush restraint function as an inrush current.

Functions 2.15 Overvoltage Protection 2.15 Overvoltage Protection The overvoltage protection has the task of preventing from insulation problems by protecting electrical equip- ment against inadmissible abnormally high voltage levels. High voltages occur in the power station sector, e.g. caused by incorrect manual operation of the excitation system, faulty operation of the automatic voltage regulator, (full) load shedding of a generator, separation of the generator from the system or during island operation.

Functions 2.15 Overvoltage Protection Setting Notes 2.15.2 General The application of overvoltage protection is only possible in 3-phase protected objects. Furthermore, it is a prerequisite that the device is connected to a three-phase voltage transformer set.

Functions 2.16 Frequency Protection 2.16 Frequency Protection The frequency protection function detects abnormally high and low frequencies. If the network frequency lies outside the admissible range, appropriate actions are initiated. For generators, e.g. the machine is separated from the network. Network decoupling or load shedding can be initiated in networks. A frequency decrease occurs when the system experiences an increase in real power demand or sub-networks that cannot (or not fast enough) be compensated by additional performance generation.

Functions 2.17 Circuit Breaker Failure Protection 2.17 Circuit Breaker Failure Protection The circuit breaker failure protection provides rapid back-up fault clearance, in the event that the assigned circuit breaker fails to respond to a protective relay. 7UT612 is equipped with one, 7UT613/63x with two breaker failure protection functions that can be used independently of each other and for different locations of the protected object, i.e.
Page 245 Functions 2.17 Circuit Breaker Failure Protection For protection relays where the tripping criterion is not dependent on current (e.g. overexcitation protection or Buchholz protection), the current flow is not a reliable criterion to determine the correct response of the circuit breaker.

With aperiodic DC current components in the fault current and/or in the current transformer secondary circuit after interruption (e.g. current transformers with linearized core), or saturation of the current transformers caused by the DC component in the fault current, it can take one AC cycle before the interruption of the primary current is reli- ably detected.
